Looking to have 2 network cards, to setup as:
#1 - > switch - > admin PCs, NAS
#2 - > switch -> user PCs, NAS
Is there likely to be any issues in having the 2 networks?
Using MS Windows 2012 Standard.
Can an ADMIN on @1 network use data held on USER PC on #2 network, or visa-versa?
Would the switches need to be separate?
Would the NASs need to be separate?

Any information on any issues that may occur would be appreciated.

Thanks.

I have a few firewalls with an enormous number of ports, several of which have been defined but are disabled for the time being.   Does anyone make an RJ45 plug with a stub of a cable that I could leave attached, and then create a label to document the unused port?

Yeah, I realize I could buy 10 3 ft patch cords and just cut them and I would effectively have this.   I was just hoping that someone had a premade cable that has a neat termination instead of a sloppy cable slice.

Please see the following two links:

http://www.cablemonkey.co.uk/cat6-bulk-cable/58-cat6-utp-pvc-solid-cable-box.html (slighty different from the first)

Are these cables ok for future proofing a new build home?  Should I consider something else?

Dear Experts,

I have a laptop that can VPN to my client's network.

What tools can I use to test if the internet is degraded?

Following on from an earlier question http://www.experts-exchange.com/questions/28906123/UK-internal-phone-cable-v-Cat-6e-cable.html#a41387422, what is the best surround sound cable I should look to include around the house to run alongside my Cat 6e cable runs to a central cable storage box / patch panel etc.

Also what type of ducting (any flexible grey pipe type) should I be using and should this contain all the individual network, phone and similar cable for each room all the way to the central hub panel room?

I am based in the UK so UK centric answers please,  and any Amazon UK example links to products will be appreciated so I can get an an example of the precise stuff I need.

Thx.

Planning to network my UK detached home as part of a rebuild.

Should I be using brush face plates to pull cables through rather than have connections to the wall for HDMI, ethernet etc etc?

Thx.

I'm building a new home and we will soon be at first fix for plumbing and electrical in the UK.

What type of wiring should I be using for an internal home phone system in the UK, can I use the same cable as Cat 6e?
Also what is a patch panel in relation to a phone system and broadband ethernet?

Any idea why I cannot get my Samsung PVR (blue ray player and HD) Device name (BDE8500M) to show on my UK Virgin Media Superbub 2 configuration settings (device list) in order to MAC filter the times in which I can block access to the internet?  The device name is showing in the settings of the Samsung PVR, but showing as blank in the broadband superhub settings.

It is currently connected via wifi.

This is a planning with the new setup, with 1 Juniper SRX240H2 16-port firewall. However, 1 Pulse Secure Gateway MAG 2600 as SSL VPN gateway is also included. Please see below on the ethernet interfaces configured on SRX240H2:

     - ge-0/0/0    Untrust, WAN port connect to Internet line
     - ge-0/0/3    DATA, Internal network
     - ge-0/0/1    BACKUP, network for backup & management, eg network for backup    
     - ge-0/0/2    Storage, network for DELL Compellent shared storage

Firewall policies, VLAN for layer 2, and IP for Layer3, routing, are also configured

Now come to MAG 2600, how can I connect it to the firewall? Shall I using "one-armed" or separate Interface (eg, create a dmz)? How shall connect the internet port 0 & 1? Please show step-by-step.

Appreciate your help in advance.

On my DELL Optiplex 9020 I am unable to connect to the internet.  Using the command prompt (Windows 10) I can ping the host server and I get a return, however that is all I can do. I have moved the ethernet cable from another PC on my desk and I still can't get anything but ping from the host server.

I am going to purchase a PCIe network today and see if it is a hardware problem.


Any ideas?

EE-Wizards,

I am looking for a NAS solution to backup up our office  systems to.  There is a budget, so the 'sky' is not the limit - between $400.00 to $700.00 for the entire solution (Meaning NAS box, Software, and HDDs).
> We are looking for a 16TB RAID-5 NAS solution.  
> Would consider TWO RAID-1 Partitions, if there is a major advantage to doing so.

I have researched some of the 'ready to use' solution on the market (i.e. Netgear's ReadyNAS 204) and even purchased and tested the ReadyNAS 204, which was a MAJOR disappointment.
?Any one have any other suggestions that do a better job than the Netgear did?

I understand that one can use FreeNAS and build a NAS, and it is here where my question lies.
?Anyone have a working/proven formula for a  build it yourself NAS box?
> I have seen some videos on this topic, but most, if not all, are pretty much dated and I am looking for an updated solution.
> We are not video streaming (Which appears the number one use of the 'self build' boxes), we are doing daily backups of our workstations Windows profile account.

Any input would be greatly appreciated.

EE-Wizards,

I recently purchased a Netgear ReadyNAS 204 and 4 'brand new out of the box' WD 4TB NAS Red Label HDDs.  I inserted all four of the the 4TB HDD and the NAS started a RAID-5 'Reshape' operation, which took 10 DAYS to complete.  Based on the Netgear Tech Support, the NAS can not be used during the Reshape operation, which makes sense, but 10 Days to do anything is an excessive time.  And i can not get a direct answer as to why this took so long, nor can they tell me how long it should take (Meaning Hours, Days, Weeks).
?Does anyone have any experience on these NAS boxes?
?Is this normal for the Reshaping (which seems to be more like a Rebuilding operation) to take this long?
?What should it take to Reshape 16TB of disk space to RAID-5?
?Do you know of better solution?

We've recently moved a switch stack for a customer and are having some difficulties with connecting some Cisco switches together.

There are 2 core switch stacks made up of 1 x 3750X and a 3750G (4 x fibre links between)
Off one of the core stacks there are then 2 more stacks hung off that with a series of about 4 3750's in each stack.

When I connect a Cisco Small Business Series SG200 switch to anywhere in the stack (which is doing L3/VLAN routing) the port goes into error mode. The guy who configured the switches said it would not be possible to connect the 2 types of switches as they were not designed to connect together, and he enabled something to error the ports when they were connected as without that it killed the whole stack due to a spanning tree election or something. Sadly I don't know enough about them to know the problem, but I see from another post that someone else is in fact using the two series of switches together with success here,

I have an HP Proliant DL308 G5 server which holds VMware ESXi-5.5.0...  I just installed server 2008 64 bit on a new virtual machine.  It's not seeing the NIC card.  The card is Broadcom Corp. NC373i Integrated Multifunction Gigabit Server Adapter.  What driver do I need and more importantly how am I supposed to install it, Datastore?

Hi
   
I need to find the cheapest / good WLAN WLAN Router available in the moment for Europe. This is for a small home. It needs also to be compatible with many different WLAN adapters and specially with Dell Wireless 1397 WLAN Mini-Card (Broadcom).
   
Many thanks for any recommendation.

Dear Experts,


I can't get my server to ping the network with the following configs:

In Brocade BR-VDX6740T:

interface Port-channel 38
 vlag ignore-split
 description itmon1
 switchport
 switchport mode access
 switchport access vlan 2
 spanning-tree shutdown
 no shutdown <---------------------------------------------------------------- fine here

sh run interface TenGigabitEthernet 2/0/38 and 1/0/38
interface TenGigabitEthernet 2/0/38
 fabric isl enable
 fabric trunk enable
 channel-group 38 mode on type standard
 sflow enable
 shutdown   <-------------------------------------------------------- It will not change to a "no shutdown" state

The brocade shows to have those two ports available for TenGig infrastructure.

Seems like a simple connection, but I cannot ping PCs on the SG300 and they cannot ping anything on the network. The 4507 is a core L3 switch which handles all Vlan and subnetwork routing. On the interface which the SG300 connects to on the 4507 I have the config:
interface GigabitEthernet4/28
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,7-11
 switchport mode trunk

On the SG300 counterpart:
interface gigabitethernet20
 switchport trunk allowed vlan add 7-11
 
 On the PC interface:
interface gigabitethernet2
 switchport mode access
 
 I have also configured:
 interface gigabitethernet1
 switchport mode general
 switchport general allowed vlan add 9 tagged
 switchport general ingress-filtering disable
 
 interface gigabitethernet4
 switchport mode general
 
 But neither of those interfaces can ping the network.
 
 When I telnet into the SG300 I can ping and traceroute throughout the entire network. When I get on the PC I get nowhere and nothing can see the PC from anywhere on the network. All the PCs, 3 of them, can see each other. The SG300 is in the default L2 mode. Vlan 1 is the ip default gateway which is the 4507. It's got to be a setting for the SG300 that I would usually not use when setting up the Catalysts.
 
What don't I see? Any thoughts greatly appreciated

I have a Wansview IP camera model NCB541W.
Until I changed my previous Router, a Linksys Wireless -G WRT54GS for a  Netgear Nighthawk AC2350 Smart Wifi, (that turned out not to be very smart), the access to the camera from the Internet worked fine.
Now with the new router I can't find the way to access the camera from the internet.
Configurations in the router are:
Port Forwarding to Camera IP at port 8080      
When I go to:  internal address of the Camera:8080, there is access.
When I go to:  external IP:8080 from any computer connected by wire (through router connection) to the home network, there is also access.
But when going to external IP:8080 from any computer not connected by wire to the network, there is no access.

Here goes a screenshot of the Router's configurations for Port Forwarding
http://screencast.com/t/dBKUMoVvjo

It looks like something in the Router is preventing the access from the external IP when the computer is outside the network or domain. I am trying to find out how to remove the firewall limitations of the Nighthawk router but cannot find any settings fro Firewall. All I have is the Port Forwarding and Port triggering features.
Any experts help appreciated

I am running Cisco Network Assistant 6.2 and have a community established with about 15 different 2960 series Catalyst switches.  I have a new Catalyst 2960S switch I am trying to add to the community.  CNA sees the switch, but when I try to add it to the community I get "Authentication Failed".  Any thoughts as to what is going on?

I have two Unifi APs. They give network access to company users on laptops and mobile devices.  I want them to also give Internet access, but not LAN addresses to guests. If I had a different brand AP, it would give addresses in a different subnet to the guests. They would then be able to connect to the Internet. It would also give either LAN addresses to registered users, or provide some sort of NAT to those users so that they could access LAN resources. Does anyone know of a way to do this on Unifi? I find that either I am very obtuse, or that the Unifi instructions are. Probably both. Thanks in advance. B. (Bill Brown)
How can I set up Unifi to do what I want?

hi I have setup the following and configured (nat pool) on sanjose1 and xp is allocated automatically 192.168.0.12/24

important: currently my broadband is down but below is a test first.

       isp-1 - 10.0.0.5/24 & loopback0 10.0.1.2/24
          |
    sanjose1 (ip nat pool configured here)
          |
lan-a switch - (int vlan 1, 192.168.0.2/24 set here)
         |
        xp - (autodetect: 192.168.0.12/24)

step 1.  if I add the following then question 1 is successful:

- no nat pool or access-list 2 permit 192.168.0.0 0.0.0.255
- xp - manually set to 192.168.0.21/24
- interfaces configured as usual
- Ip route 0.0.0.0 0.0.0.0 10.0.0.6
- ping 10.0.0.5 - successful
- ping 10.0.1.2 - successful

step 2.  if I add the following:

- ip nat pool added as per config on sanjose1
- ip route 42.0.0.48 255.255.255.240 10.0.0.6 - question 1 step 2 unsuccessful
- ip route 0.0.0.0 0.0.0.0 10.0.0.6 - question 1 step 2 unsuccessful
- ping 10.0.0.5 - fail
- ping 10.0.1.2 - fail

important:  xp autodetects & shows - default gateway set as 192.168.0.2 - I assume this is because the dhcp is configured via ip nat pool on the sanjose1 router and the sanjose1 int s0/0 is set as 192.168.0.1/24 - so ok as ip nat pool should automatically allocate addresses to lan-a.

question 1.  step 1 above - successful but step 2 - fail - I wish to be able to allow xp to ping isp-1, loopback0 & int s0 10.0.0.5, but it cannot ?

question 2. I think I need to configure some dhcp command on lan-a 2950 switch  ?

Hi Experts,

I was speaking to someone yesterday who told me that you could physically split an Ethernet cable, lets say Cat5e in order for 2 PoE phones to work. I have had a thought about this and I am assuming that this is because the cabling has 8 wires and a phone connection usually only has 4 therefore you could take the 4 that you need and put that into one wall socket and take the other 4 and put it into a different wall socket.

the reason for the request is this will stop us from needing to run additional Ethernet cables throughout the building as we could just split the ends in the comms room and the ends at the walls!

anyone done this before? anything to consider? is it even possible?

I am not able to log into the web interface of a Motorola WS 2000 Wireless Switch.  Everything was working just fine and then one day the device quit broadcasting its SSID and nobody could connect to it.  I had to power cycle the unit to reboot it and everything worked as usual except I could not log into the web interface.  I kept getting a message “Login Failed Cannot Connect to WS 2000”.  I had the correct username and password but could not log into the unit through a web browser.  I found an article on how to connect through a serial cable, bring up a console and reset the password to the factory default.  I did that; reset to factory default then rebooted the system, and reconnected via console.  The unit made me change from the default password to a user selected one, which I did.  I then tried to log into the device via a web browser and still received the same message “Login Failed Cannot Connect to WS 2000”.    

Ever since the device locked up and quit broadcasting I have not been able to access it through its web based interface.  I am able to pull-up the login page but not able to login.

The system is working.

Intel network cards offer an option to increase the number of send and receive buffers, but says it should probably not be necessary.  I do have occasional network issues, probably unrelated to the buffers.  My machines have ample memory, so increasing the buffers is not an issue there.  However, too many buffers can adversely affect performance.  Does anyone have any real world experience as to whether the number of buffers matters?
